DM4149.The coordinates were established by GPS observations
DM4149.and adjusted by the National Geodetic Survey in June 2019.
DM4149
DM4149.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM4149.been affixed to the stable North American Tectonic Plate.
DM4149
DM4149.The coordinates are valid at the epoch date displayed above
DM4149.which is a decimal equivalence of Year/Month/Day.
DM4149
DM4149.Due to the release of the International GNSS Service (IGS) 2014
DM4149.realization of the International Terrestrial Reference Frame of 2014
DM4149.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM4149.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM4149.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM4149.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM4149.currently published epoch of 2010.00.
DM4149
DM4149.Additional information on MYCS2 is available at

DM4149.Significant digits in the geoid height do not necessarily reflect accuracy.
DM4149.GEOID18 height accuracy estimate available here.

DM4149.The XYZ, and position/ellipsoidal ht. are equivalent.
DM4149
DM4149.The ellipsoidal height was determined by GPS observations
DM4149.and is referenced to NAD 83.
